Federal authorities in New York City announced the criminal charges against SAC Capital Advisors on Thursday. SAC is charged with wire fraud and four counts of securities fraud, but owner Steven Cohen is not charged.

The Galleon Group founder also was fined $10 million. U.S. District Judge Richard J. Holwell announced the sentence after concluding that Rajaratnam made well over $50 million in profits from his illegal trades.
